* Contributions are Copyright (C) 2001-2008 Paritosh Pungaliya.

* Objective of the additional terms (license) 
* 1) Is to extend the software freedom to freedom to work.
* 2) To ensure that knowledge is free from monopoly of agencie(s).
* 3) To avoid a situation where big corporates or investors can buy out free software groups and companies and then start milking the communities built around it.
* (this trend can be seen how the openness changes in companies that get Venture Capital funding.)
* (if you agree to this logic I invite you to our group to work together)

* Additional conditions
*  0) Source code will also include
* 	a) data dictionaries, data ontologies which are used to alter the behavior of code or to control           the features of application.
* 	b) Any code generated or derived automatically or manually from this code or logic
*  1) The revenue generated by deploying, implementing , selling services and other activities
*  	 based on this source code should be shared 100%, between the people working on it.
*  2) Capital invested should be given only fixed rate of return or linked to revenue/surplus growth for limited time.
*  3) People working on the project should always have an option to replace the capital provider in full or part with lower cost capital.
*  4) Their should not be any ownership which can be sold as a claim on future profit to be generated from the work of people working on the code.
*  5) Brand thus generated should belong to the group.
*  6) For old and new members revenue sharing should be equal for same work equivalent.
*  7) The share of revenue should be decided by bidding for work before allocation of work within the group.
*  8) Before bidding various method of measuring the work should be clearly defined and published in public domain. Any change in process should also be publised in public domain imediately.
*  9) All data related to to revenue sharing should be published as and when generated in public domain.
*  10) For group of people having size more than 10 people will have to make it open online for others to participate in bids. 
*  11) All people involved in related and sub project will be treated as a group.
*  12) Once this license is being used for a certain code then all and any other software services being provided by the group should complusorilly come under 100% revenue sharing.
*  13) Cross subsidization should not happen under this revenue share, no additional benefit should be drawn from the people, by the employing agency.
*  14) Any position or knowledge or legal structure created relating to people working on code, which adversely affects the spirit of 100% revenue share will be treated as a violation.
*  15) Revenue sharing defined.
*     a) includes direct revenue and also intangible gains like brand, and organization.
*     b) No personal judgment should be involved in judging the distribution of revenue.It has to be pre-defined formula based.
*     c)100% of revenue should be shared before expenses and recievers should have control over what expenses to incur.
*     d)For the work done in any month by contributing group member, working on any project can be given revenue share from the work done by the group, for a maximum of 18 months after that month.
*     e)Revenue should be apportioned to the month in which work is done and not when received.
*  The group fulfilling the above conditions also has to be a wiki ecosystem further defined in www.wekosystem.org or read about Wekosystem at www.wikiocean.net
